8-3/4 hard to turn the wheels

Contacted Doctor Diff. He is the one the axles and bearings came from. I have drums, so he said I didn't need to remove the thrust button, but if he did, it is not a problem. Normal to be harder to spin than an 8-1/4, even a lot harder, and 2x as hard to spin backwards. I will contact the shop who assembled it and ask him tomorrow, and pull the shaft to check for ease.

Thanks
